Advanced Wearable Sensing Technologies for Sustainable Precision Agriculture – a Review on Chemical Sensors

Abstract

Crop production is impacted by increased plant diseases and shifting environmental circumstances. Monitoring plant health is necessary to raise crop quality and productivity to meet population growth demands. Nanotechnology‐based sensor platforms provide real‐time plant monitoring capabilities, going beyond the constraints of conventional sensor technologies. Wearables are an evolving area of health monitoring and have been modified for agricultural purposes.  Wearable sensors are placed on various plant organs in the agricultural industry to check the crops’ health continuously. The varieties of wearable sensor materials and their fabrications, followed by their sensing mechanisms, are highlighted in this review. Furthermore, monitoring plant micro‐environmental factors, including salinity, hazardous gases, and pesticides, are discussed. This text covers various internal plant growth factors monitoring, such as sap flow, transpiration, and signal monitoring. The challenges of wearable sensors in agriculture are mentioned toward the end.
